Explain your thinking,and include a statement of the solution. I think it is 8,912x1,000 on a place value chart, Is that what i am supposed to do??

I have figured out how to do it but I am not sure to divide or multiply

Yes, the multiplication you show is correct.
If 1 branch has 8,912 butterflies, and the estimate is that the total number of butterflies is 1000 times this amount, then there are 1,000 * 8,912 butterflies altogether.

To multiply by 1,000, just move the decimal point 3 places to the right.
For example, 1,000 * 5 = 5,000
1,000 * 75 = 75,000
1,000 * 2,000 = 2,000,000

Now try 1,000 * 8,912
